About Max-Air Air Line Visual Moisture/CO Indicator

Knowing when there is too much moisture or carbon monoxide (CO) in the breathing medium is important the MI-4000 Moisture/CO indicator is what will let you know if you are pumping wet air or high CO air. MI-4000 is the visual moisture/CO indicator with site glass and color-metric elements for both CO and Moisture. This detector consists of a visual" indicator (#MI-4000), into which a small (15mm diameter) disc is inserted. The visual' indicator has a clear sight lens through which the disc may be seen. The disc changes color in the presence of low concentrations of carbon monoxide within 5 to 10 minutes of exposure and therefore acts as a clear visible warning before the proportion of gas reaches an unacceptable level. If higher and more dangerous concentrations or carbon monoxide are present, the disc changes color within a few seconds.

The detection disc is specially treated to prolong its life. A color change from tan to dark grey will occur in the presence of carbon monoxide. The rate if change of color is directly related to the concentration of carbon monoxide present. The detector will change color in five to ten minutes at 50 100 ppm of carbon monoxide, but will change color within a few seconds if the level reaches 500-1,000 ppm (0.05%-0.1%), at which concentration it can be lethal. When saturated the disc turns black. The moisture disc indicator will turn from blue to yellow or sandy brown when moisture is detected. The detector is a quick, inexpensive and simple means of showing the presence of carbon monoxide in the sample air. There is no need for troublesome sampling equipment or expensive analytical equipment. The change in color is easy to spot and the results can be interpreted by non- specialist staff. The MI-4000 Moisture/CO indicator is compatible with the following Max-Air Compressors: SKU's MXA35, MXA90 and MXA90G
